Background: Most theoretical models of self-determination suggest that both environmental and personal factors influence the development of self-determination. The design and implementation of interventions must be conducted with foreknowledge of such mediating and moderating factors if the intervention is to be successful.
Methods: The purpose of this study was to examine the degree to which several personal factors and school characteristics affect and explain students’ self-determination. A total of 232 students with intellectual disability from Spain participated. Their self-determination level was assessed by the ARC-INICO Scale.
Results: Students with moderate levels of intellectual disability obtained significantly lower scores on self-determination than their peers with mild intellectual disability. There were significant differences in relation to the level of support needs and their experience with transition programs. The level of support needs was a significant predictor.
Conclusion: These findings contribute to current research in this field and practical implications were discussed. 相似文献
Introduction: The rising prevalence of musculoskeletal pathologies in developed countries has caused a dramatic impact on social welfare. Amidst these musculoskeletal pathologies is Rheumatoid arthritis (RA), a chronic systemic autoimmune disease that mostly affects the synovium. RA metabolic-associated alterations, including distorted adipokine production, enhance RA inflammatory environment. Among the altered adipokines, visfatin is particularly involved in RA inflammation and catabolism and stands out as an essential enzyme linked to critical cell features.
Areas covered: We discuss the potential mechanism supporting the contribution of visfatin to RA and the association between RA and obesity. We discuss the repurposing of cancer-tested drugs to inhibit visfatin in the context of RA. Additionally, we address the possibility of combining these drugs with current RA therapy. Finally, we explore the future of visfatin as an RA biomarker or therapeutic target.
Expert opinion: Inhibition of visfatin has become an interesting therapeutic approach for RA pathology. Such a feat has already been attained in oncology using small molecule inhibitors, which suggest that a similar course of action would be worth pursuing in the RA context. Visfatin will become an important biomarker and therapeutic target for RA. 相似文献

Pituitary metastases of solid tumours are infrequent, specially as a first manifestation. When they happen, they are usually
due to breast or lung cancer and are asymptomatic or produce diabetes insipidus. It is very strange that they produce hormonal
deficiency.We present a case report of a bronchogenic adenocarcinoma in a 65-year-old man which began with panhypopituitarism, diabetes
insipidus and visual alterations. Magnetic resonance imaging revealed a large sellar mass, with clivus infiltration and invading
the right cavernous sinus. The biopsy result was adenocarcinoma metastases from lung cancer.相似文献
The synthesis of new N3-arylciclohexanespiroimidazolidine-2,4-diones, N3-arylciclohexanespiroimidazolidine-2-tio-4-ones and the 4-hydroxy derivatives is described and their structures discussed on the basis of I.R. and 1H-N.R.M. data. The anthelmintic activity of these compounds was tested. 相似文献
A gene fragment encoding for the amino acids (aa) 286-426 from the dengue Envelope (E) protein was expressed in Escherichia coli as two forms of fusion proteins. In one case, the E fragment was fused to the first 45 aa of the P64k protein from Neisseria meningitidis (PD2) while, in the other, it was inserted within the lipoil-binding domain of the aforementioned bacterial protein (PD3). PD2 was obtained as insoluble form within the cytoplasm of the bacteria while PD3 was distributed equally as soluble and insoluble forms. The insoluble forms of each protein as well as the soluble fraction of PD3 were semipurified to test the antigenicity and the immunogenicity in mice. The forms containing the entire P64k protein exhibited the highest recognition with different polyclonal and monoclonal antibodies. Consequently, the neutralizing antibodies elicited by the recombinant proteins were higher in the case of PD3 forms than with PD2, independently of the solubility status. In addition, mice inoculated with the semipurified insoluble form of PD3 were partially protected against lethal challenge with dengue-2 virus, administered by intracerebral inoculation. The results suggested the folding and carrier capacity of the P64k protein over the E fragment, converting PD3 as an attractive vaccine candidate against dengue-2 virus. 相似文献
The activity of 5-deoxy-5-fluorouridine (dFUR) depends on its activation to 5-fluorouracil (FU) by pyrimidine nucleoside phosphorylases. These enzymes are found in tumors and normal tissues, with the highest activity in the small intestines. The present study examined the inhibition of dFUR phosphorolysis in intestinal tissues. dFUR metabolism in intestinal homogenates was inhibited by uracil (U), uridine (UR), and thymidine (TdR), which are the normal substrates for the phosphorylases. Conversely dFUR reduced the metabolism of these inhibitors. A good agreement was found between the observed data and the computer-fitted data using the equations for competitive inhibition between dFUR and the inhibitors. In the absence of inhibitors, the Vmax of dFUR phosphorolysis was 47.1 ± 4.9 µM/min and the apparent Km was 910 ± 167 µM. The Vmax was unaltered by the inhibitors, while the Km was increased with increasing inhibitor concentrations. The maximal inhibition of dFUR metabolism by UR and TdR was about 80%. The Ki,'s were 372 µM for U, 87.2 µM for UR, and 112 µM for TdR and are orders of magnitude higher than their reported endogenous serum concentrations. The rate of dFUR phosphorolysis to FU in the intact intestinal epithelial crypt cells, indicated by the ratio of FU to dFUR in the intracellular fluid, was reduced by UR in a concentration-dependent fashion. These data indicate that the naturally occurring pyrimidines inhibit competitively the dFUR metabolism by the intestinal phosphorylases, that this inhibition occurs at concentrations much higher than the circulating endogenous levels, and that phosphorolysis is the major route of dFUR metabolism. 相似文献
An evaluation is made of the effect of smoking during the period of life between 20 and 50 years of age and idiopathic Parkinson's disease in a case-control study carried out in Navarra. An inverse association is observed: for the number of smokers (OR = 0.66, CI 90% 0.41-1.05); for the number of years smoking (OR =0.22, CI 90% 0.05-0.97); and for the quantity of cigarettes smoked (z = 2.2298, p = 0.02). Likewise, a dose-response relationship exists between the number of cigarettes consumed and the risk of Parkinson's disease (p = 0.01). The same effect is maintained on analysing the data by matching 1:1 (OR = 0.59, CI 90% 0.31-1.10). All of this contributes to giving consistency to the protective effect of smoking against idiopathic Parkinson's disease. The anti-oxidant status, measured by means of different parameters in peripheral blood, is lower in the cases than in the tests for reduced glutathione (GSH) (p = 0.001) and is an independent variable with respect to smoking. 相似文献
